Raw data table for yeast experiment

There should be no variation in the precision of the data; the same number of decimal places significant digits should be used.

Draw the table either by hand or within a software program like Microsoft Excel or Google Sheets. Be sure to include a row for the heading of each column. After some time, the bead rises to the surface of the hydrogen peroxide solution. Be sure the table does not break across multiple pages. The test tube that produced the highest volume of oxygen in the gas syringe shows the optimum temperature of the yeast. When the hydrogen peroxide decompose, oxygen and water is produced. The glass rod hydrogen peroxide to be drops would be then be of the longer or shorter, also same sizes. The enzyme in the yeast is known to lower activation energy and catalyse the decomposition reaction. This is because the collision between substrate and the active site happen more frequently at higher temperatures due to faster molecular motion. Hence, the bubbles observed during the experiment are oxygen bubbles. The rate of enzyme The amount of oxygen given A gas syringe can be activity can be out when hydrogen peroxide connected to the test tube and investigated in another decompose cannot be the volume of oxygen way quantified and it would be produced in 30 seconds can 9 unable to tell when the be collected and measured in enzyme has denatured. Alumni Data Tables Presenting data in an effective way is an important skill of all scientists. The yeast alginate There would be an unequal To ensure the yeast is evenly mixture has not been distribution of yeast distributed, this can be stirred homogenously. This is because heat causes vibrations inside enzymes which break bonds needed to maintain the structure of the enzyme.

When you're finished there should be a number in every space. Oxford pg Teo Yu Qing Teo Yu Qing IB 1 Principled Effect of a factor on enzyme activity in yeast Controlled Variables: Controlled Variables Method of Controlling Significance Variable Volume of hydrogen Use a syringe to measure Having different volumes peroxide used should be 5cm3 of hydrogen of hydrogen peroxide will kept constant peroxide, at eye level affect the amount of hydrogen peroxide used during the experiment.

This can be seen from Table 1, where time taken for the alginate bead to rise and reach the surface of the hydrogen peroxide solution decreases as temperature increases.

When the beads were dropped into the hydrogen peroxide solution, bubbles were observed on the sides of the test tube and around the beads. The glass rod hydrogen peroxide to be drops would be then be of the longer or shorter, also same sizes.

Be sure the table does not break across multiple pages. Label the columns, including units and measurement uncertainty of the raw data. Rows are a series of horizontal cells and columns are a series of vertical cells. There should be no variation in the precision of the data; the same number of decimal places significant digits should be used. Different volumes of hydrogen peroxide will affect the amount of oxygen produced, thus affecting the time taken for the bead to rise and reach the surface Concentration of yeast Make sure that only 0. The yeast alginate There would be an unequal To ensure the yeast is evenly mixture has not been distribution of yeast distributed, this can be stirred homogenously. The Decomposition of Hydrogen Peroxide. The hypothesis also states that beyond optimal temperature, the enzymes in the yeast would denature and the rate of enzyme activity would decrease, causing a longer time taken for alginate beads to rise and reach the surface. Sometimes it is helpful to break a large table into several smaller ones to allow the reader to identify important information easily, but, conversely, it is a common mistake of students to split up into several tables data that belong in one table. However, the reaction would take a long time. The enzyme in the yeast is known to lower activation energy and catalyse the decomposition reaction. This is because the collision between substrate and the active site happen more frequently at higher temperatures due to faster molecular motion.

Draw the table either by hand or within a software program like Microsoft Excel or Google Sheets. However, this hypothesis has not been demonstrated in the experiment.

Hence, the bubbles observed during the experiment are oxygen bubbles. Hence, the data collected may not be very reliable. The processed data Table 3 have shown some percentage errors that are more 1 Angela Howard.
